DHT21 Temperature and Humidity Sensor AM2301A

DHT21 Temperature and Humidity Sensor AM2301A

The DHT21 temperature and humidity sensor is an advanced sensor unit that provides calibrated digital signal output. It is highly reliable and stable in long-term operations. It contains an 8-bit microprocessor, providing fast and quality response.

It measures temperature between -40 and 80°C with an accuracy of +/-1°C and can measure humidity between 0-100% RH with an accuracy of +/-5% RH. Due to the sensor's data collection period, measurement results can be obtained at 2-second intervals. The DHT21 is somewhat larger in size compared to other DHT models.
